Cycled just fine the first two times.

This (the third) time we're just going to replace the trim.

Took setpoint and cycled.

Plotted on the same Y-axis are three signals -- Total RF trips in 60min rolling window, NL RF trips and SL RF trips in same 60min rolling window.

We have gone from <15 RF trips an hour most of January, to this weekend at times >20 some hours, or an RF trip every <3min. Most of this increase appears to be from the SL, green trace.

Logged in at the Principal Investigator #1 Desk, opsl06.

Tried to execute the command in an x-term but get same error.

Am I doing something wrong here?

Launched alarm viewer from JMenu -> Operations -> Alarms -> Alarm Viewer
(another Operator has tried this as well, and his JMenu command call is throwing an error, separate PR to come)

Upon loading in, get Figure 1, nothing found.

Figure 2+3: Setting up for a query for the past hour, same thing, nothing found.

Tried the same query, but this time clicking the Get All Messages checkbox. Nothing found.

Alarm Disable Tool appears to be functioning properly. All CEBAF alarm handler trees have heartbeats.

Am I missing something mid-Owl-shift haze?

Figure 1: Before and after trip fwd power, reflected power, phase, and vernier, from top to bottom.

First, before checking Pass1 separation, had to finish out the LEM-fudge-LEM of SL after de-rating 2L08-1 to try and improve VBV2L08B open-time.

Figure 2: C-beam as -found. Figure 3: A-beam. Figure 4: B-beam.

This should be good enough.

First tried remote reboot of iocmc1, but ended up hanging. Took two hard reboots to get IOC back up. Crash recovered, but still don't have 30Hzsync, and iocse17 and 20 still do not as well.

Perhaps related, hard reboots of iocmc1, Pass1 RF separator tripped off.
